Subject [jira] [Commented] (HIVE-8795) Switch precommit test from local to local-cluster [Spark Branch]
Date Wed, 12 Nov 2014 18:45:35 GMT

    [ https://issues.apache.org/jira/browse/HIVE-8795?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14208436#comment-14208436

Szehon Ho commented on HIVE-8795:
---------------------------------

Hi Xuefu, I thought last time we could not get it work (after Rui and my attempts) as some
spark code was looking for a spark script in a predefined path.  Did something change in the
meantime?

>  It seems unlikely that Spark community will provide MRMiniCluster equivalent (SPARK-3691),
and Spark local-cluster was the recommendation. Latest research shows that Spark local-cluster
works with Hive. Therefore, for now, we use Spark local-cluster (instead of current local)
for our precommit test.
> It's previous belived (HIVE-7382) that a Spark installation is required and SPARK_HOME
env variable needs to set. Since Spark pulls in Spark's assembly jar, it's believed now we
only need a few script from Spark installation instead.
